PHILIP K. STOCKTON, OF ST. HELENA, CALIFORNIA.

SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 275,956, dated April 17, 1883.

Application filed August 5, 1882. (No model.)

To all whom it may concern:

Be it known that I, PHILIP K. STOCKTON, of St. Helena, county of Napa, State of California, have invented an Improved Vineyard Sulky-Plow; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful sulky-plow specially adapted for use in vineyards or for the plowing of all kinds of plants which are in rows, such as corn, hops, &c.

My invention consists in combining a righthand and a left-hand turning-plow, or two or more of them, on aframe, so as to face to ward each other or away from each other, the plows being movable on said frame, so that the furrows can be thrown, two or more at a time,toward the center or away from the center.

Referring to the accompanying drawings, Figure 1 is a perspective view of my sulkyplow. Fig. 2 is a plan of the same.

Let A represent an axle having wheels 13; The axle may be acrank-axle, and the device may be provided with any suitable means for raising and lowering, which I shall not here explain.

0 is the frame. This consists of strips of iron a, converging forward of the wheels and bolted to the tongue Gr. They extend back parallel to each other, are secured to the axle, and thence extend to a cross end, I). To these strips, back of the axle and upon the outside, are bolted strips 0, diverging past the rear of the wheels as far beyond their line as desirable, and thence parallel to the cross end I), to which they are bolted. Between the cross end b and the diverging strips 0 are bolted strips 01, and between the forward or converging portion of one of the strips to and the rear portion of the other strip a is bolted a zigzag strip, 6, which makes two turns or bends back of the axle.

D D are curved plow-standards secured suitably to the rear or parallel portions of strips a. Their lower ends are split and diverge, and are bolted to and support the plows E E, one end being bolted to the moldboard and the other to the landside. One of the plows, E, is adapted to turn the earth to the right hand and the other, E, to the left hand.

F is the seat suitably supported and braced from the frame. In using this device the plowsE E are successively shifted to the strips d and c to make new furrows without changing the line of travel of the horses. By projecting upon each side of the standards the plows are enabled to get under the vines, whether they be in position shown to throw the earth to the vine, or whether they be reversed to throw the earth from it, as the season may demand. One of the plows I shift to the forwardbend of the zigzag strip e and the other to the rear bend in throwing out the center or dead-furrow. In this position their points travel in the same line and their moldboards turn the earth away from the center.

In the entire operation I use but two horses. They do not change their line of travel, but continue in the middle of the row, and the shifting of the plows enables me to make the furrows up to the vines and to cultivate both sides of the row at once. When the first furrows are being made the horses and wheels travel on level ground, and likewise when the second series are being made, as the plows travel in line behind the wheels. It is only in making the outside furrows that the wheels and horses travel in the broken ground.

It will be seen that, if I desire to put more than two horses in, I can do so, andcan utilize their power by increasing the number of my plows, making all on one side turn in an opposite direction.

In fields where the length and breadth justify leaving turned rows next the fence sufficientfor four or more horses to be swung, the plow will be useful as a four or six horse gang. By placing three right-hand plows on the left side of the frame and three left-hand plows on the right side, forming two sides of a triangle, the point being under the axle, the center row can be turned to the center at one journey, or,

vice versa, away from the center and to-the vines.

I am well aware that in side-hill plows the plowis made to swing round and turn either right or left, and I do not claim such a plow.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a vineyard sulky-plow, the axle A and wheels B and the frame 0, in combination with a right-hand plow, E, adapted to-be sel yond the wheels, and parallel at their ends,

cured or shifted to any of the longitudinal strips upon one side of the center of the frame, and a left-hand plow, E, adapted to be secured or shifted to any of the longitudinal strips upon the other side of the center of the frame, substantially as herein described.

2. In a vineyard sulky-plow, the axle A, wheels B, and frame 0, consisting of strips (6, converging to the front and parallel behind the axle, strips 0, diverging behind and bei cross-strip I), short strips d, and zigzag inclined strip 0, all arranged as shown, in combination with the right and left hand plows 15 E E, and standards connecting them with the frame, substantially as herein described.

In witness whereof I hereunto set my hand.
